Resumen

In this paper we describe a new tool being currently developed by Eurocontrol for Air Traffic Control multiradarmultisensor data processing systems assessment. This tool, called TRES (Trajectory Reconstruction and Evaluation Suite), will become in a near future a replacement for some parts of current versions of SASS-C (Surveillance Analysis Support System for Centres) suite. The paper describes the overall architecture of the assessment system, and details the methods used in TRES for the calculation of reference trajectories, taking into account sensor detection characteristics, available information, sensor accuracies, biases, ... The whole system has been tested with real traffic and simulated data, some illustrative examples are presented at the end.
